How are "what" different from regular nuclear reactors? The question has insufficient information in it to be properly answered. Please restate the question.
Please elaborate on "they" as no comparison can be given otherwise. Do you mean?: "How is nuclear fusion different from regular nuclear reactors (nuclear fission?)"
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
The most common coolant used in nuclear reactors is water. There are light water reactors (using "regular" water), and the heavy water kind of reactor.
Nuclear reactors use nuclear fission.
The breeder reactor produce more fissile fuel than what is consumed while this is not the case for other nuclear reactors.
A breeder reactor generates (in a way) new fuel, sometimes more fuel than it uses, by converting non-fissionable isotopes into fissionable isotopes, through neutron capture.
There are 59 nuclear reactors in France.
We use nuclear fission in nuclear reactors to tap nuclear energy.
Current nuclear reactors rely on nuclear fission as their nuclear reaction.
There are over 400 nuclear reactors around the world.
there are no bad things about the nuclear power reactors
As of 2010, India has 20 Nuclear Reactors.
